The problem that I suspect that you're running into is that tftp will often "float" its port numbers....meaning that the initial contact is made to the tftp server on port 69, with the source port being a higher port number, then when the tftp server responds, it will use the port that the client sourced the connection from along with its own high port number...this means that the tftp "connection" (its udp, so its not a "true" connection in the tcp sense) no longer uses port 69 at all. This may be where your firewall is running into problems. :/
Yeah, I started seeing all sorts of random ports being hit, so I just opened up all tcp/udp between the tch and laptop. Now it went ahead and erased flash, then crapped out. Just sitting there. Nothing in the firewall logs showing what's up, and it's real addresses behind the fw, no nat. I like "copy tftp://some.server/path/to/code slot0:" much better :) C
